Abstract

1383426 Ammoxidation catalyst MONTECATINI EDISON SpA 16 June 1972 [16 June 1971 21 July 1971 15 Sept 1971 (2)] 28439/72 Heading. B1E [Also in Division C2] A catalyst containing tellurium, oxygen, and either titanium or cerium or molybdenum, or containing tellurium, oxygen, cerium and molybdenum, the atomic ratio of tellurium/ cerium or titanium when present in the catalyst being from 1/0.1 to 1/5, the atomic ratio of tellurium to molybdenum when present in the catalyst being from 1/25 to 1/0.5, and the atomic ratio of the tellurium, cerium, and molybdenum when present in the catalyst being represented by the formula: where x=0.2 to 20, y=0.5 to 20 and z=1 to 30, is used in the preparation of α, # unsaturated nitriles from the reaction of saturated aldehydes with molecular oxygen and ammonia.
